To all whom t may, concern.'

Be it known that we, EDWARD G. WAT- KINs andk CHARn-EsA. BROWN, both citizens of the United States, residing at Gardner, in the county of l/VorcesterV and Commonwealth of Massachusetts, have invented a new and useful Improvement' in Combined School Desks and Chairs,of which the following, together with the accompanying drawings, is a specification.

The present invention relates to a combined school desk and chair, of the type adapted to be set up in rows of considerable length. The invention is embodied in a chair and a desk supported on a single base, the chair being used in connection with the desk of the structure immediately in front, and the desk being used in connection with tlhedchair of the structure immediately be- The invention resides in the novel features of construction by which both the desk and the chair are made adjustable, entirely independent of one another, and by which the support of the two devices upon a single base is so arranged as to prevent the transmission of shocks and jars to the desk.

The invention is fully set forth in the following description and illustrated in the accompanying drawings, in which Figure 1 is a side View of the combined desk and chair.

Fig. 2 is a plan view of the supporting devices, the desk and the chair seat being shown in broken lines.

Figs. 3 and 4 are plan and sectional views, respectively, of the means used to secure the chair seat to its standard.

Like reference characters refer to like parts in the different figures.

The invention comprises a base casting 1, having a bottom flange 2 of extended area, for attachment by screws or the like to the floor. Substantially concentric with the flange 2, the base provides a polygonal opening 3 to receive loosely a polygonal standard 4, one side 5 of which is tapered downwardly. A set screw 6 carried by the base bears against the side 5 of the standard, and when tightened, securely retains the standard at the height to which it is adjusted in the opening 3 by crowding the opposite corner of the standard into the corresponding corner of the opening. The inclination of the side 5y )preventsy the standard from dropping suddenly when the screw 6 is loosened; `The upper end of the standard passes through a plate 7 fastened to the underside of the seat 8 of the chair 9, and is headed, as at 10, or otherwise attached to the plate, in order to secure a rigid connection with the chair.

The base 1 vhas a rearwardly extending web 11, providing a tubular enlargement 12, which receives the lower end of a standard 13, held securely therein by a pin 14, or other device for preventing rotation of said standard. The standard 13 is polygonal in cross section, one of the sides 15 thereof tapering upwardly. A bracket 16, attached to the underside of a desk 17, has a portion extending forwardly of said desk which provides a polygonal opening 18 fitting loosely over the standard 13. Said bracket carries a set screw 19 bearing against the inclined side 15 of the standard; said set screw when tightened against the standard crowds the opposite corner of the opening 18 against the corresponding corner of the standard and thereby, in conjunction with wedgeshaped standard 13, securely holds said bracket and desk at the height to which they are adjusted. The inclination of the side 15 prevents the bracket from dropping suddenly when the set screw 19 is loosened` and also, when the screw jars loose, the wedging action of said standard, as the bracket descends by gravity, causes the tightness and rigidity of the parts to be maintained.

By the construction above described, the desk 17 and the chair 9 are rendered independently adjustable, so that any height of either member may be obtained, irrespective of the height to which the other member is adjusted. The invention thereby affords a decided advantage over prior devices of this class which provide a single standard rising from the base, and supporting a pair of adjustable brackets, one above the other, one for the desk and the other for the chair. Furthermore, by the present construction, the seat is supported directly over the center of the base, so that vibration of said seat is impossible, since the maximum of rigidity is obtained. The support of the desk, upon an independent standard rising from the base, effectually avoids the transmission of shocks and jars, incident to the occupation of the seat, to said desk. Furthermore, the overhanging support aEorded by the Web 11 and enlargement 12 for the desk 17, insures the provision of a sufficient space for the feet of the occupant of the chair used in connection with said desk, c'. e., the next chair in the row.

We claim:

1. As an article of furniture, a combined school desk and chair, comprising a single base member having an extended supporting surface, and having an integral extension overhanging said supporting surface, means for adjustably supporting said chair on said base member in alinement with the center of said extended supporting surface, and means for adjustably supporting said desk above and from said overhanging extension.

2. As an article of furniture, a combined schooldesk and chair, comprising a single base member having an. extended supporting surface, and having an integral extension overhanging said supporting surface,

a chair supporting standard adjustably received in said base member, in alinement with the center of said extended supporting surface, a second standard rising from the end of said integral overhanging extension of the base member, and a desk supportin bracket adjustable on said .second standar Dated this sixth day of January, 1916.
